OCULUS offers two precision Mirror-Exophthalmometers. Both use reflection mirrors to measure the position of the globe accurately, even after tumor removal or thyroid decompression. Both deliver fast, reproducible results. The primary difference lies in the way each design is positioned and supported.
With the Hertel, the unit is held in both hands and held firmly against the left-hand orbital rim in line with the center of the cornea. Supports are placed against the two temporal orbital walls, so the orbital rim contacts the deepest point of the supports.
